• Partially ordered set
• Representation
• Differentiation algorithm
• Adjoint functors
• Projectivization

Adjoint functors and projectivization in representation theory of partially ordered sets are used to generalize the algorithms of differentiation by a maximal and by a minimal point. Conceptual explanations are given for the combinatorial construction of the derived set and for the differentiation functor.
